check your LCD's cable. i have this problem with mine currently as I had a torn spot on the ribbon. I just ordered another LCD.

Make sure you have your 5v+ going into the first motor port

Yeah, this has been an issue for manned aircraft, sadly by changing the definition of aircraft (albeit unconstitutionally, as congress already defined it and excluded hobbyist in FAR sec 336), they have gained the power to do that.

Try setting your throttle mid just a bit higher.

So are you adjusting the expo on the FCB or Tx? Expo stands for exponential. Here is a quick example of the effects of exponential gain y represents the output signal or power for your purposes, and x is how far the stick is. The purple line represents a 'throttle curve' with expo, and...

Looks odd, without having a way to experiment with it, I'd say return it.

If your quadcopter is stable leave the PIDs to be as they are hahaha, but if the quad has too much throttle for your controls adjust the stick scaling AKA expo, and maybe the throttle authority in motor mixer if that is available to you and only as a last option. Your ESCs or flight controller...

If you have an RX plug it in and see how exactly it moves, looks like some sort of servo powered catch. Oops, the last message was never submitted hahaha, now that I think about it I think ringolong is right.

Do you have a receiver? Also do they have any numbers? I could ask around.

for Ohio from a US warehouse I am getting a little under 70, and DC is not too far from me.

Post the link you bought, sounds like the batteries did not charge, have you any way to test them?

I wrote this answer in response to this question("Why are quadcopters so stable?"), and decided I might as well post it here also. Multirotors unlike helicopters or planes are inherently unstable like a rock. If you were to power each motor up to the exact same speed it is unlikely you would...

Yeah, what is what I am thinking.

Looks like it may be a copy, if that does not mater for you then it also looks like your parts are only rated for 3S, so the same battery in 3S would work.

Looks liek the correct place to post it to me hahaha. Good guide.

Wish I could like that 100 times hahaha.

What type of budget are you talking? @Mike H.

Yes haha, you get used to it and it is harder to quit. I have tried it, but can never get the hang of it, as it feels really weird.

Can you get a video of it again?
